Inter-entity borders are no determined on natural geographical featurs o the region. Its borders wur postulatit as pairt o the poleetical greement that wis based on ethnic diveesion an are uised tae determine the extents o poleetical jurisdictions athin entities. On the grund there is nae active border atween RS an FBiH an ane wad generally no ken the difference when crossin frae ane entity intae anither.

The ceety o Brčko in northeastren Bosnie is a seat o the Brčko destrict, a sel-govrenin admeenistrative unit unner the sovereignty o Bosnie an Herzegovinae; it is pairt o baith the Federation an Republika Srpska. The destrict remains unner internaitional superveesion.

The Federation is further dividit intae cantons, which are then subdividit intae municipalities. Republika Srpska is dividit directly intae municipalities.

On the grunds that the Dayton Greement's framewirk is ootdatit, mony groups hae come fort with weys tae redevelop the diveesions o Bosnie an Herzegovinae. The greement wis initially designed tae effectively end the war in the naition, but the diveesions hae made the bureaucracy o the kintra unwieldy.

Generally speakin, the naition's Bosniak population wishes for the state tae be centralizit, eliminatin the Federation, as well as the Republika Srpska. Offeecials in the Republika Srpska vehemently resist this idea. Mony Serbs assume that if Kosovo achieves unthirldom, Republika Srpska will separate frae Bosnie an Herzegovinae, eventually joinin Serbie. Housomeivver, the Office o the Heich Representative haes come oot an specifically denied the prospect o ony such exchynge. The Bosnie Croats view the current situation as discriminatory, an seek either the abolition o entities an foondation o a decentralizit govrenmental structur or a third entity.
